Lightest car tow dolly available, only 330 lbs. Easy for any retiree to pick up and maneuver. Built in hydraulic brakes, no need for additional braking system. My spouse had 3 neck surgeries, no longer able to get under car to hook up safety chains. We prefer Dolly, over flat tow, as you can tow any vehicle. Gently used 5 times. Includes extra brand new straps, 2 brand tries. Shipping extra if unable to pickup.
